Still, anger and pride gave him the necessary strength to conceal from the spectators the frightful agony he was suffering: by a supreme effort of the will he resumed an apparent calmness, and fired again.

"That is better," El Rayo said mockingly, "but a little too high. Try another."

Exasperated by this fire, don Felipe pulled the trigger.

The bullet struck the rock about an inch above the stranger's head.

Only one bullet was now left in the revolver.

"Advance five paces," said El Rayo; "perhaps you will not then throw away your last chance."

Without replying to this cutting sarcasm, the officer bounded like a wild beast, stopped at fifteen paces, and fired.

"It is now my turn," the stranger said, as he fell back five paces to re-establish the distance; "you forgot to take your hat off, caballero, and that is a want of courtesy which I cannot tolerate."

Then drawing one of the pistols thrust through his belt, he cocked it, stretched out his arm and fired without taking the trouble of aiming. The officer's hat was hurled from his head and rolled in the dust.

Don Felipe uttered a howl like a wild beast.
